Sometimes, when the system start to load the kernel, or when I start X, in the scrren appears a lot of flashing lines, and is difficult to read something. So I must do "startx" or kill X (it depend if I were out or in X) to solve the problem. It appears the first time on kernel 2.6-test9 benh3, with new radeon driver, so I suppose the problem Is of this driver. On stable 2.6.1-r1 the problem appears 1-2 times a month; in 2.6.4 it appears often. Reproducible: Sometimes Steps to Reproduce: 1.Use a kernel > of 2.6-test9-benh3. With 2.6.4 is sure you see this problem, and try to load kernel some times and do startx. Actual Results: A lot of lines flashing on my screen, and If I am not in X, I the same charatters in more than 1 line flashing. Expected Results: Don't have this annoyng problem. With 2.6.3* this problem is very big. You can see other graphic problem, so I think it is a radeon driver problem.
The image isn't good, but you can see some strange lines at the middle of the screen. These lines are flashing.
please 1 emerge info 2 describe better your hardware 3 is that the radeon framebuffer driver? 4 could you check the development-sources 2.6.5? (the ppc-development-sources currently masked will give you more problem than help)

the 2.6.5_rc2-ben0 ebuild has a wip framebuffer support and may have issue with powermanagement. could you try the 2.6.5 as in the development-sources ebuild?
I want to try it, but it is for x86, and no for ppc. Shall I edit the development-sources ebuild and add ppc?
I see the problem on 2.6.5-rc2 too.... Now I am using 2.6.5 and no problem yet.
the development-sources ebuild is marked ~ppc now, closing
I see the problem on 2.6.5 development-sources too
same problem here. appears seldomly and is hard/impossible to reproduce on purpose. looks as if the display is running with wrong sync settings. dimming the display down and up again (effectivly switching it off/on i believe) fixes the behaviour. doesnt seem to be related to X, also happens in framebuffer console mode. kernel: 2.6.7-gentoo-r11 hardware: G4 15" Alu Powerbook 1.5ghz, latest modell with "Powerbook5.4" in /proc/cpuinfo
This problem should probably reported upstream. What happens if power management, pbbuttonsd, pmud are all disabled?
closing upstream
